LMES Product Info Distribution Guide

1. Functional Overview

The Product Information Distribution process is a core function in the LMES system used to automatically distribute product-related information to equipment. When a product enters a station, the system automatically transmits data such as product model, work order information, and process parameters to the equipment (e.g., PLC), ensuring that the equipment can produce according to the correct parameters.

1.1 Main Uses

• Automatically distribute product model and work order information when the product goes online
• Distribute corresponding process parameters (temperature, pressure, time, etc.) based on the product model
• Transmit product formula information to the equipment control system
• Distribute quality standard parameters to testing equipment

2. Workflow

2.1 Process Steps

The entire distribution process includes the following steps:

1. Start Process

   ↓
4. Query and Distribute Product Info
   ↓
5. Return Distribution Result
   ↓
6. Wait for Equipment Confirmation
   ↓
7. Reset State, Ready for Next Distribution

2.2 Flowchart

3. Usage Configuration

3.1 Enable Process

In the Process Segment Configuration, find the "Product Information Distribution" function:

• Enable: Select "Enable" to activate this function
• Disable: Select "Disable" to turn off this function

3.2 Variable Configuration

You need to configure the following 4 variables to communicate with the equipment:

Variable Name	Variable ID	Description	Required
Trigger Signal	ProductInfoDistribute_TriggerSignal	Equipment notifies LMES to start distribution	Yes
Product Code	ProductInfoDistribute_SerialNumber	Unique identification code of the product	Yes
Distribution Result	ProductInfoDistribute_Result	Execution result returned by LMES	Yes
Result Description	ProductInfoDistribute_Description	Detailed description of the result	No

3.3 Distribution Parameter Configuration

Configure the parameters that need to be distributed in "Process Settings":

1. Enter the Process Settings interface
2. Select the corresponding product model and process
3. Click the "Product Info Distribution Settings" button
4. Configure the parameter items to be distributed
5. Save the configuration

3.3.1 Configuration Interface Description

The Product Info Distribution Configuration interface is used to set which parameters need to be distributed to the equipment and where to distribute them.

Interface Structure:

The configuration interface is divided into two parts:

1. Top Information Area: Displays the context of the current configuration

   • Product Model: Displays the currently selected product (e.g., XH1)
   • Current Process: Displays the process currently being configured (e.g., Process 2)

2. Configuration List Area: Displays and edits distribution parameter configurations

Configuration List Field Description:

Field Name	Description	Remarks
Data Source	Select where the parameter comes from (Collection Parameter, Formula Parameter, Material Parameter, Product Parameter)	Also known as "Parameter Source" or "Type"
Data Source Name	Which specific parameter to select	Lists available parameters based on the data source type
Process Name	Displays the process associated with this parameter configuration	Can be the current process or another process
Distribution Type	Where the parameter is distributed to (Variable or Formula Process Value)	Also known as "Distribution Target"
Distribution Data	Specifically which variable or formula process value to distribute to	Also known as "Target Location"

Relationship between "Current Process" and "Process Name":

• Current Process (Displayed at the top): The process that triggers the product information distribution flow

  • For example: Current Process shows "Process 2", meaning when the product is executed at Process 2, the product info distribution flow will be triggered.
  • This is the trigger point configured, i.e., at which process to start the distribution.

• Process Name (Column in the list): The process where the parameter source is located

  • Indicates which process the parameter to be distributed comes from.
  • For example: Process Name shows "Process 1", meaning the parameter distributed is a parameter defined in Process 1.
  • If you see multiple identical process names, it means distributing multiple parameters from Process 1.

Usage Scenario Description:

Suppose the interface shows:

• Top: Product Model XH1, Current Process: Process 2
• In the list:
  • Row 1: Data Source = Product Parameter, Data Source Name = Product ID, Process Name = Process 1
  • Row 2: Data Source = Product Parameter, Data Source Name = Product Name, Process Name = Process 1

This means:

• When the product is executed at Process 2, the product info distribution flow will be triggered.
• The parameters distributed come from Process 1 (Product ID, Product Name).
• The system will distribute these parameters from Process 1 to the equipment.

Typical Application Scenarios:

• When the product is at Process 2 (e.g., SMT process), it is necessary to distribute the parameters collected in Process 1 (e.g., Loading process).
• Or at Process 2, it is necessary to distribute the basic information of the product and the process parameters of Process 1.

3.3.2 Parameter Source Types

The system supports 4 parameter sources:

Source Type	Description	Example
Collection Parameter	Collection parameters defined in the process	Process parameters such as temperature, pressure, speed, etc.
Formula Parameter	Parameters defined in the product formula	Formula version, formula number, etc.
Material Parameter	Parameters related to materials	Material number, material batch, etc.
Product Parameter	Attribute parameters of the product itself	Product model, product name, work order number, etc.

3.3.3 Distribution Target Types

The system supports 2 distribution targets:

Target Type	Description	Usage Scenario
Variable	Distribute to equipment variable	Directly distribute to PLC variables for equipment use
Formula Process Value	Distribute to formula process value	Distribute to formula parameters for formula execution

8. Usage Example

8.1 Example Scenario

An electronic product production line needs to distribute SMT parameters in the SMT process:

Preconditions:

• "Product Info Distribution" function is enabled in the process segment
• 4 communication variables are configured
• Product info distribution parameters are configured in process settings:
  • Product Model → Variable Product_Model
  • Work Order Number → Variable Order_Code
  • SMT Temperature → Variable Process_Temperature
  • SMT Speed → Variable Process_Speed

Operation Steps:

1. Product arrives at SMT station, scanner reads product code: SN202411200001
2. PLC writes product code to variable: ProductInfoDistribute_SerialNumber = "SN202411200001"
3. PLC sends trigger signal: ProductInfoDistribute_TriggerSignal = 1
4. LMES system automatically:
   • Reads product code
   • Queries work order info for this product (Product Model: iPhone-15-Pro, Work Order: WO20241120001)
   • Gets parameter values to be distributed according to configuration in process settings
   • Distributes parameters to PLC:
     • Product_Model = "iPhone-15-Pro"
     • Order_Code = "WO20241120001"
     • Process_Temperature = 250
     • Process_Speed = 1.2
5. LMES returns result: ProductInfoDistribute_Result = 1 (Success)
6. PLC reads distributed parameters and starts SMT operation
7. After operation completes, PLC sends confirmation: ProductInfoDistribute_TriggerSignal = 0
8. LMES resets state: ProductInfoDistribute_Result = 0
9. Process ends, waiting for next product

8.2 Failure Handling Example

If distribution fails:

1. LMES returns: ProductInfoDistribute_Result = 2
2. LMES returns description: ProductInfoDistribute_Description = "Product model not found"
3. PLC displays error information to prompt operator
4. Operator checks:
   • Is product code correct?
   • Does this product have a corresponding work order?
   • Is the work order distributed to this process segment?
5. After the problem is resolved, re-trigger the distribution flow
